• If you are trying to use Boolean operators, they must be ALL CAPS: fang sheng ((yan je) OR (yang jui)) ((chin chang) OR (china chang)) wang kyoung yun ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "fang sheng ((yan je) or (yang jui)) ((chin chang) OR (china chang)) wang kyoung yun ;~".
• Adding a wildcard symbol may retrieve word variants: fang sheng ((yan je) or (yang jui)) ((chin chang) OR (china chang)) wang kyoung yun ;*.
